Semantic relationships

Prerequisite and related edges are what make this a graph rather than a menu.

Misconceptions

Stored on the entity so worksheets, quizzes and lesson plans all target the same known errors.

Misconception

Students treat counterexamples as a rule to memorise rather than a relationship to understand.

Correction — Anchor the rule in a visual model first, then abstract it — the model is the explanation.

Misconception

Learners apply the correct method to counterexamples but ignore the context or units.

Correction — Require an answer sentence with units on every applied question.

Curriculum alignment

Curricula, boards and countries are data — adding one never changes the architecture.
